MUSIG-LEAF TURNER.

Specification of Letters Patent.

Patented Jan. 19, 1915.

Applieation filed February 5, 1914. Se1ia1 N0. 816,732.

T0 all wh0m it may concern Be it known that I, HUNTER DENNIS a citizen 01 the United States, residing et Exeter, in tl1e county of Tulare and Stute o1": California, l1ave invented certain new anal useful Improvements in MusicLeaf Turners, of Which the following is a specification, reference being liad to the accompanying clrawings.

This invention relates to new und useful improvements in music leaf turners end more particularlv to a music leaf turner for application 130 a piano anal the primary object of the invention is to provide a clevice 0f this clmracter Which Will be most efiicient in carrying out the purpose for which the same is designed.

A further object of the invention resicles in providing a clevice 01' this character Whieh is readily operatecl by the actuation of the foot 01 the operator and a still further objeot resicles in provicling a device Which is simple und durable in construction, inexpensive to manufacture anal one which Will be very eflicient und useful in operation.

lVith these und other objects in view, the invention consists in tl1e novel features o1 construction, combination und arrangement of parts as Will be hereinefter fully clescribecl and claimecl.

In the accompanying drawings forming a part of this application, Figure 1 is a f1ont elevation of 21 clevice constructecl in accorclance with my invention applied to use on a piano. Fig. 2 is a vertioal section through the piano ancl leer? turner haken on line 22 Fig. 1. Fig. 3 is a plan view thereof. Fig. 1 is a cletail section as seen on line 4: 1, Fig. 2, disclosing the lower operating mechanism. Fig. 5 is a cletail elevation of one of the supports for the cord guicling mechanism at the top of the piano. Fig. 6 is a similar view partly in section otf the upper swinging arm or crene.

In clescribing my invention, 1 shall refer to the clmwings in Whieh similar reference characters designate corresponding parts throughout the several views and in wbich- 1 designates a piano of the upright type ancl on the front i'aee thereof above the key board, is mounted a music raek 2. As herein embodied, the mal: 2 comprises a skeleton frame 3 of rectangular design which is hingeclly mountecl 011 a shaft or rod, as is believecl to be self-evident.

My invention primarily contemplates the prov1snon of an improvecl 11162LI1S -Eor turning the movable frame o1 the music rack refer1el to above und, to this encl, an arm 5 is mountecl 1or pivotal movement 011 the top 6 01: the piano about cencrally o1 the latter 011 the forward edge 01 the same. This arm may, for eonvenience, be termed a crane und the szune is pivotally mountecl in a bezuing 7 providecl Witli bearing balls. The outer encl of this arm 01 cmne 5 is proviclecl With a ball o1 knob 8 designecl 1or engagement with tl1e upper portion of the moval5le frame 3 of tl1e music mehr. Conneetecl 110 the outer end 01' this movable arm o1 orane 5, are tl1e flexible members 9 and 10, Whi0li ere formed of rope, Wire 01 cable, as desired, ancl extencling in opposite directions. Also mountecl on the top G of the piano and projecting outwarclly therefrom, on opposite sicles 01 ehe bearing 7, are the sationar3 arme 01' supports 11 Which a1e slottecl longituclinally ancl hzwe tl1e flexible me1nbers 9 and 10 guiclecl therethrough. Pivoted at 12 to the inner encls 01" the mms 11, are the snnging arme 13 whicl1 are adaptecl to swing through the slots 01 ehe arm 11 und the outer ende o1 these swinging arms 13 are proviclecl With pulleys o1 rollers 14: over Whieh are trainecl ehe flexible members 9 und 10. Thus these swinging ar1ns tend 130 position the flexible members 9 ancl 10 so as to readily operate the arme 01 crane 5 when seid flexible niemloers are clmwn in one clirection o1 tl1e other. As statecl, the flexible members 9 ancl 10 are guiclecl over the rollers 01 pulleys 14, alt tl1e outer encls 01 the swinging arm 13 ancl the szune are ben directed und guiclecl through openings 01 cl1annels 15 formecl in the L-op 0 of Ehe piano adjacent the sicle eelges thereof. The ope1h ings or channelways 15, just referrerl to are acljacent be forwarcl eclge of ehe top, outer sicle of the souncling boarcl 16 of the piano anti be flexible oonneetions 9 and 10 which are disposecl througl1 seid channels o1 openings are also tminecl over a plurality 015 pulleys or rollers 17 arrangecl in the piano forwarcl of this sounding boarcl. These pulleys are so arrangecl es to dispose the lower portions o1 tl1e flexible connections parallel with one another ancl seid connections are directed to points adjacent the bottom of the piano.

Mounted on the bottom of the piano, just forward of the sounding board, is a supporting post 18 which is slotted at its upper end at 19 and has a somewhat V-shaped crane er arm 20 fulcrumed therebetween, the fulcrum point being indicated ab 21. This ost 18 is braced by means of a bracing arm 22 and the outer ends of the arm 20 are provided with the adjustable eye bolts 23, the latter being connected with tl1e lower ende of the flexible connections 9 and 10.

A pedal member 24 is hinged at its inner end at 25 to tl1e sounding board 16, adjacent the lower elge of the latter, said edal being disposed through a slot in the front face of ehe piano adjacent tl1e bottom 0f the Same. This pedal member l1as a stirrup 01' U-shaped member 26 secnred thereto and is pivoted at 27 to one arm of the V-shaped a'rm 20. A spring 28 has one end thereof engaged with tl1e bottom of the piano and its other end disposed beneath tl1e edal to hold the latter normally in its elevated or hdrizontal position. Tims, it Will be seen that when it is desired to turn one of the leaves 0f ehe musie rack, it is only necessary to press downwardly upon the pedal 24, which operation Will rock the member 20 on its fulcrum point on the post 18 and draw upon tl1e flexible member 9. By drawing on this flexible member, the upper crane 5 will be drawn toward the left and carry with it the hinged frame 01. the music rack. When the .lt'oot is released from the pedal 24-, the latter will be retnrned 150 its initial po sition uncler compression of the spring 28 and by the returning 01 this pedal, the mem ber 20 will also be returned to its initial po sition to draw upon the flexible conneetion 10, and drawing of this connection will return tl1e crane or arm 5 to its initial position. It Will thus be seen that the frame 3 of the rack may be readily turned by a slight foot actuation of the pedal 2-1.

From the foregoing description of the construction 0f my improved devioe, the manner of applying the same to nse and the operation thereof Will be readily understood and it Will be seen that I have provided a device which is simple and durable in construction, inexpensive to manufacture and one which W1ll be very efiioient and useful in operation.

While I have particularly described the elements best adapted to perform tl1e innotions set forth, it is obvious that various changeg in form, proportion and in the minor details of construction may be resorted to without departing from the spirit 01 sacrificing any of the principles of the invention.

Having thus described tl1is invention, what I claim is: y

1. In a musie leaf turner, the combination with a support, and a swinging frame carried thereon adapted to receive sheets of music thereon; oit' an arm pivotally carried on the top of said support and projecting outwardly therefrom, said arm being adapted for engagement with the swinging frame to turn the latter at predetermined times, stationary arms projeoting outwardly from the support, said arms being provided With longitudinal slots, additional arms pivotally carried by the stationary arme and movable through tlie slots thereof, pulleys carried on tl1e outer ende of said last named arms, flexible connections engaged witl1 said first mentioned arm and extended in opposite directions therefrom, said flexible eonnections being also trained over tl1e pulleys, and 1neans engaged wit-h the ends oi said flexible connections for drawing npon the latter and correspondingly actuating said first mentioned arm whereby to actuate said swinging frame.

2. In a music leaf turner tl1e combination with a support, a swinging arm carried thereon, and flexible connections engaged with said swinging arm to actnate the latter upon ehe actuation of said flexible oonnections, said flexible connections being gnided on the support at points adjaoent the bottom oi t-he latter; of a supporting pst mounted on tl1e bottom 0f said supporting member and having the upper end thereof bifnrcated, an arm i'ulcrumed intermediate 0f its ends in ehe bifurcated end of said post, means engaged with ehe outer ende of said arm for adjnstably connecting ehe lower ends of said flexible connections thereto, a pedal 1nember hinged at its inner end on said support, below said fulcrnm arm, means for connecting said pedal member to one exten sion 0i said fulorum arm to actnate the latter upon the actuation 0f the pedal member, and spring means in connect-ion with said pedal member and tl1e bottom 0f said support to normally dispose said pedal member and parts carried thereby in a precletermined position.
